Ford, GE and University of Michigan team up on sensor to track EV battery life, keep us on the road
Believe it or not, EV battery life is still something of a Pandora's Box, even for automakers: they can tell you the battery pack's current and voltage, but not how it's really performing under pressure. Ford, GE and the University of Michigan are uniting to unlock that mystery through a new ARPA-E project. In its role, GE is developing a minuscule sensor array that will track the nuances of battery cells that existing technology misses; it will promptly hand the baton to researchers at the University of Michigan, who plan to both prove that GE's data is on the mark as well as develop tricks for predicting behavior. Ford handles the last mile, almost literally: it's planning to fit the GE sensor technology to one of its cars and test in a more realistic environment. Before you fantasize about knowing the lifespan of your Focus Electric's battery down to the minute, however, the new alliance is stressing that it's only just getting started -- there's another three years and $3.1 million to go before the project wraps up. If all goes according to plan, though, we'll have electric cars and plug-in hybrids that can not only tell when they've seen better days but can eke out extra miles through smarter battery designs.
DHS looking to satellites, mesh networks for emergency communications
Seeking to avoid the communication breakdowns that occurred as a result of the September 11th terrorist attacks and the Hurricane Katrina disaster, the Department of Homeland Security is developing an emergency network that would let officials email one another even in the absence of a cellular infrastructure. The DHS' Advanced Research Projects Agency, which is analogous to the Pentagon's DARPA, is looking at a number of options to keep the data flowing following an emergency, including widespread deployment of mobile mesh networking technology or re-purposing some of the government's legacy satellites to handle terrestrial communications. This latter option is particularly attractive because some sats could offer transfer rates in excess of 100Mbps, and in fact a trial program is scheduled for this summer that will employ modified BlackBerries and Treos to send secure, satellite-based email between Homeland Security officials and the Royal Canadian Mounted Police.[Via Smart Mobs]
